Power Transducer Series L-UNIT

BIDIRECTIONAL CURRENT TRANSDUCER

Functions & Features

• Accepting 3-phase/3-wire AC current and voltage and

detecting the magnitude and direction of the power flow by

the phase angle of the signals

• Providing standard DC signal in proportion to the AC

current

• DC output containing little ripple is ideal for computer

input

• Isolation up to 2000V AC

• High-density mounting

Typical Applications

• Measuring AC current flow in a factory having private

power plants

MODEL: LCY–1[1][2]–[3][4]

ORDERING INFORMATION

• Code number: LCY–1[1][2]-[3][4]

Specify a code from below for each [1] through [4].

(e.g. LCY-11A-C/Q)

• Special output range (For codes Z & 0)

• Specify the specification for option code /Q

(e.g. /C01/S01)

CONFIGURATION

1: 3-phase / 3-wire

[1] INPUT (balanced load)

Current

1: 110 V AC / -5 - +5 A

2: 110 V AC / -1 - +1 A

3: 220 V AC / -1 - +1 A

4: 220 V AC / -5 - +5 A

The negative polarity of input current indicates the direct

(surplus) flow and the positive indicates the reverse flow.
